Forget Al Roker. When it comes to today’s extended weather forecast, it’s all about Punxsutawney Phil. So, in honor of Groundhog Day, here are five fun facts you might not know about this legendary little critter and his 127-year-old tradition.

1. Let’s start with the basics. Groundhog Day takes place every year on Gobbler’s Knob in Punxsutawney, PA (hence his name). If he sees his shadow, it’s six more weeks of winter. And if he doesn’t, it will be an early spring.

2. The day has roots in both an ancient Christian holiday called Candlemas and a Celtic festival called Imbolc.

3. Following the 1993 release of the Bill Murray movie, Groundhog Day, crowds reached over 30,000.

4. Made up of a group of 15 local dignitaries (dressed in suits, top hats, and all), the Groundhog Club’s Inner Circle is charged with planning the event and taking care of Phil.

5. For the majority of the year, Phil resides with his “wife,” Phyllis, in a climate-controlled home in the Punxsutawney Library.
